San Jose, Calif. – Power Integrations announced that its 200 V Qspeed diodes – LQ10N200CQ and LQ20N200CQ – are now available with AEC-Q101 automotive qualification. Qspeed silicon diodes use merged-PIN technology to offer a unique balance of soft switching and low reverse recovery charge (Qrr). This results in low EMI and reduced output noise, which is especially important for in-vehicle audio systems.
The newly qualified 200 V diodes feature the industry’s lowest reverse recovery charge, typically 32.4 nC at TJ of 125°C, and a diode softness ratio of 0.39. This minimizes high-frequency EMI inherent in the Schottky rectifiers often used in Class-D power amplifier output stages. Dual 10 A and 20 A common-cathode diodes are housed in the industry-standard, rugged DPAK TO-252 package.
The LQ10N200CQ and LQ20N200CQ diodes are produced in IATF 16949-certified facilities. Devices are available now; the LQ10N200CQ and LQ20N200CQ are priced at $0.60 and $0.74 respectively in 10,000 quantities.
